KNOCKDOWN BOX.

Specification of Letters Patent.

Patented July 6, 1909.

Application filed August 31, 1908. Serial No. 450,994.

To all whom it may concern:

Be it known that I, OnAnLEs O. MENGEL, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful Improvements in KnockdownBoxes, of which the following is a specification.

My present invention pertains to improvements in knock-down boxes, theconstruction and advantages of which will be hereinafter set forth,reference being had to the annexed drawings, wherein: Figure 1 is aperspective view of the box in its collapsed condition; Fig. 2 asectional perspective view of the same when assembled; and Fig. 3 asectional view of a slightly modified structure.

The main object of the invention is to produce a simple, light and yetefficient knockdown box for the transportation, primarily, of materialin bulk.

Referring first to Figs. 1 and 2, the sides (which term. includes thetop and bottom of the box) 1, 2, 3 and 4, have their proximate edgesbeveled, as at 5, and the intermediate members, 2 and 3, are connectedto each otherand to the sides 1 and 1 respectively, by wire hinges 6.Said hinges are formed of two interlocked loops, the ends of which arepassed inwardly through the sides and, after being carried along againstthe inner face of the sides, are driven into the same, whereby thehinges are securely held in place. Upon the inner face of each side andat each end thereof is secured a cleat 7, said cleat having at each enda beveled face 8, the angle of which is coincident with the angle of theadjacent beveled edge 5. At one end the cleat is cut away to one side ofthe beveled face, thereby forming a squared recess 9, While at theopposite end of the cleat is formed a square tongue 10, complemental insize to the recess 9. The heads 1.1 and 12, and also the sides, arepreferably formed of compound lumber, said heads being of such size asto accurately fit the openings formed by the sides when the same arebrought to their closed or folded position, as shown in Fig. 2. Theproximate edges of the sides 1 and 4 may be secured in place by wires 13passed through holes 1 1 formed in said sides, or through eyelets 15mounted therein.

Under the construction as above set forth, the material within the boxis depended upon to hold the heads in place against the cleats. Theformation of the cleats renders the box stiff and stable.

Where it is desired to position without depending upon the materialwithin the box, extra cleats, as 16, Fig. 3, may be secured to thesides, said cleats being spaced. away from the cleats 7 a sufficientdistance to permit the heads to pass between the same.

No claim is made herein, per se, to the sides connected. by the wirehinges, as that forms the subject-matter of a separate application filedby me of even date herewith.

Having thus described my invention, What I claim is:

1. In a knock-down box, the combination of a series of sides, theabutting edges of which are beveled; wire hinges securing the sametogether; heads a cleat mounted upon the inner face of each side and ateach end thereof, said cleat having a beveled face at each end. whichstands in alinement with the adjacent beveled edge of the side; a tongueformed upon one end of the cleat to one side of the beveled face andadapted to fit into a complemental recess formed in the end of the nextadjacent cleat; a second series of cleats secured tothe inner faces ofthe sides at each end thereof, said series being spaced away from thefirst cleats to form a recess for the reception of the heads and meansfor securing the parts in their closed position.

2. In a knock-down box, the combination of a series of sides theabutting edges of which are beveled; wire hinges formed of interloopedmembers connecting the same; a cleat secured to the inner face of eachside and adjacent to each end thereof; heads of a size to fit within thesides when the same are brought to their closed position; and means forsecuring the parts in their closed position.

3. In a knock-down box, the combination of a series of sides theabutting edges of which are beveled; Wire hinges connecting the same; acleat secured to the inner face of each side and at each end thereof,each of said cleats being formed at each end with a hold the heads inbeveled face which stands in alinenient with cleats being likewiseprovided at one end name to this specification in the presence of With asquared recess and at its opposite end two subscribing Witnesses. with asquared tongue; heads adapted to fit Within the sides when the same arefolded; CHARLES MENGEL' and means for securing the parts in theirWitnesses: closed position.
